MACHINE FOR STRINGING TAcs.

SPECIFICATION forming part of Letters Patent No. 356,101, dated January18, 1887.

Application filed June 14, 1886. Serial No. 205,186. (No model.)

To all whom, it may concern:

Be it known that I, CHARLES H. DANA, J r., a citizen of the UnitedStates, residing at West Lebanon, in the county of Grafton and State ofNew Hampshire, have invented certainnew and useful Improvements inMachines for Stringing Tags; and I do declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being bad to the accompanying drawings, and to theletters and figures of reference marked thereon, which form a part ofthis specification.

The object of my invention is to provide an improved machine forstringing tags, the knot fastening the string being what is commonlycalled a"slip-noose; and my invention consists in details ofconstruction described below, and pointed out in the claims.

In the drawings, Figure 1 is aside elevation. Fig. 2 is a plan Viewbelow line w m, Fig. 1, the cam lever omitted, showing the rigidslide-hook, the toggle-arm hook, and the pincher-shears starting fromthe left to carry the twine in two loops or three parallel courses tothe tag-plate on the right. Fig. 3 is a like view, the pinchershears,the slide-hook, and toggle arm hook having carried the twine loopspartly above and below the tag-plate, the. pinchershears being abouttorelease one end of the twine in order that it may be carried upthrough the hole in the tag by the grip rod and hook to form a looseknot, (see Figs. 7 and 8,) and the hooks being about to move out of saidloops as the slide travelsto the left again. Fig. 4 is a sectional sideelevation showing the position of the parts when the slide has nearlycompleted its left throw, the pinchershears gripping the twine totighten the knot, the twine being severed just after theslidereverses,when the parts are as in Fig. 2. Figs. 5 and 6 are sectionalviews of opposite sides of the pincher-shears. Figs. 7, 8, 9, and 10 aresectional perspective views of the tag-plate and tag, showing differentstages in the formation of the knot. Fig. 11 is a detached view of thehook and grip-rod. Fig. 12 is a plan viewof the twine-looping devices,most of the machine being broken away and the slide having moved to theright of the position shown in Fig. 2. Fig. 13 is an end view lookingtoward the hooks a a when as shown in Fig. 12, certain parts of themachine being removed. Fig. 14 is a transverse section of thepincher-shears removed.

Like letters refer to like parts.

A A is the frame. At one side of it is a way, B, and its top is inclinedtoward the frame. (See 1), Figs. 2, 3, and 11.) On this incline rests aslide, O,whose bottom is correspondingly inclined.

O is the drive-wheel on the end of shaft 0 journaled in the frame. (SeeFig. 2.) From a pivot, a, on said wheel the pitmau D extends to theslide, a headed bolt, a, passing through the' pitma-n, the washer a andthe slide, and it will now be seen how the slide is moved back andforward on the way. To the outer side of the slide (see Figs. 1 and 2)is screwed a right-angular strip, 0, the horizontal part of which isabove the top of the slide and terminates in a hook, a bent slightlydownward to easily take under the twine or draw out of it. At a there ispivoted to the top of the slide and under hook a a togglearm, 0,provided with a hook, a for taking over the twine, (see Fig. 2,) andjointed by pin a to toggle-arm Cfiwhich is pivoted to afixed center, 0,on the frame, and guides the arm 0" in its horizontal play.

C is the twine-spool, from which the twine passes about one of the pins7) Hand under the ring-shaped weight or tension 0 Thence it passesthrough the raised guide I) on arm and through hole b in armO, the freeend being firmly gripped by pincher-shears E.

Referring to Figs. 1, 5, and 6, the gripping and shearing device will bedescribed.

-E is the cutting-blade, pivoted between a shear-plate, E and agrip-plate, E the latter being at a higher level, and having its toprounded at d. The blade E is beveled above the cutting-edge, (see cl,Fig. 5.) Therefore when the blade descends the twine will be firmlygripped between the edges d d; but just after the slide starts on itsright-hand throw the blade descends to the top of the shearplate E andsevers the twine, leaving, however, the end of the twine running fromthe spool still gripped between the blade and the plate E (see Fig. 4.and also Fig. 2,) where the twine has just been cut. The shear actionwill be further referred to in the descrip- I also at d to the end ofthe angular extension F of the pitman. (See Figs. 1 and 3.) There forethe throw of the pitman governs the grip and cut of the blade E.

G is the feed or tag plate. It has two foldedover edges, G G, (see Fig.2,) which serve as guides as the tags are fed under the corner,

and also prevent the twine from touching and displacing them. As theseedges are beveled toward the working parts and incline upward,

the twine cannot foul. The plate G has a U-shaped slot at f (see Fig. 2)to permit the descent of the grip-hook through the eyelet of the tag,which operation will be described later on, and underneath is providedwith a stop, G, having a shoulder, g, for arresting the twine extendingfrom the pincher-shears to the toggle-arm hook a when the parts assumethe position of Fig. 3, until the grip hook and rod descending take holdof the twine and then draw it up through the tag, the shears releasingtheir grip just before the latter operation.

The mechanism for operating the grip hook and rod will now be described.To the frame at e, (see Fig. 2,) is pivoted the bent arm H. At 0 (seeFig. 1) is pivoted a cam-lever, H, the lower bent end of which enters aslot, 6 (see Fig. 3,) in the slide 0, and is pivoted therein by the bolta before mentioned. will now be seen that as the slide moves back andforth the lever H will. raise and lower arm H. The end of said armnearest the lever is vertically bored out and screw-threaded abouthalf-way down. In this bore is inserted a hollow threaded sleeve, Hwhich is thus rendered adjustable up or down. This sleeve terminatesbelow in a rigid hook, h. Playing in the hollow of the sleeve isgrip-rod H attached by a pin,-z', to lever H slotted at 2", and pivotedto arm H at Extending from arm H through lever H is a headed pin, K,surrounded by a spiral spring, k, whose normal action is by pressing onlever H to hold down the grip-rod H to clutch the twine between the endof said rod and the barb of hook h. About the pivot e (see Figs. 1 and4) the lever H is formed in the shape of a cam,

L, and on the back side of this are two diagonally-opposite pins, Z Z.Between the cam and arm H there is attached to pivot e a dog, M, havinga shoulder, at, and on lever H* is a roller, N, engaging with the camand allowing the spring to lower the grip-rod H, or lifting said rodwhen pin Z has forced the dog under the roller, the lever H being liftedup against the spring (see Fig. 4) until the pin Z, returning to theposition in Fig. 1, has knocked the dog back again. It may be statedthat the dog holds up lever H during a large part of the down movementof arm H, and that the down throw of rod H into hook h is ofcomparatively short durationthat is, during the stringing of the tag andthe loosest stage of the knot.

A description of the operation will showhow the parts 'act at differentstages, and is as follows: The knot is begun when the slide has juststarted on its right throw. (See Fig. 2.) The hook a is under hook a,and as the slide moves hook a catches over the twine and hook a underthe twine, nearer hole 12 and this operation separates the twine intotwo loops or three parallel courses. The slide having reaohedits rightthrow, (see Fig. 3,) the stretch of twine from hook a to hook a, beinghighest,

is carried above the corner of the feed-plate,

while the twine from hook a to hole I) is carried just under the plate,but above the shoulder 9 of stop G. The twine running from hook a to thepincher shears, being lowest, strikes shoulder 57, where it is inposition to be clutched by the grip-hook 71, (see Fig. 1,) whichdescends through the slot of the feed-plate and the eyelet of the tagafter the other courses of twine pass under said hook. The slidinggriprod now descends by the action of the cam L and the spring icon thelever H and holds the twine in the barb of the hook h. Thepincher-shears now open and release the free end of the twine, and it iscarried up through the tag I coming from the spool trailing back throughthe shears to the tag, the ring-weight O giving enough tension to drawthe knot nearly tight. When the parts are as in Fig. 4., the rising rodH has just freed the twine from hook h and the blade E has gripped thetwine between the edges dd, (see Figs. 5 and 6,)and at this point therun of the twine through the shears is stopped and the knot begins tofurther tighten. When the slide reaches its left throw, the. shears drawthe knot tight. As the slide starts again on its right throw the twineslackens, and is cleanly cut by the blade E and the top of theshear-plate E when the tag may be removed and another fed in before hookh reaches the feed-plate. After the twine is cut the end of it extendingback to the spool is still held by the gripping parts of the shears (seeFig. 2) where the twine has just been cut, and is about to be carried tothe feed plate again, as in Fig. 3. Referring again to the fact that thedog M holds up lever H* during a larger part of the down motion of armH, or until pin l knocks the dog away from roller N, I would say thatthis is important, as it gives ample time for withdrawing the tags, andI ICC . ent, is

1. The combination, with the moving slide operated substantially asshown, ofthe pinchershears, the twine-looping hooks, the feed-plate, anddevices, substantially asdescribed, for drawing the free end of thetwine up through the plate and eyelet of the tag, as set forth.

2. The combination, with the slide, of the pitman, the pincher-shears,the twine-looping hooks, the feed-plate, the grip-hook, and thegrip-rod, operating, substantially as shown, in conjunction with saidhook to draw the twine through the plate and tag and to release thetwine before the shears tighten the knot, as set forth.

3.

6. The combination, with the feed-plate G, having folded-over edges G G,slot f, and shouldered stop G of the hook it and grip-rod H and theslide 0, provided, substantially as shown, with attached devices forgripping, looping, and carrying the twine to said plate, as set forth.

7. The combination, with the drive-wheel, of the pitman, the slideprovided with attachments, substantially as shown, for gripping,looping, and carrying the twine, the way B, the cam-lever H, pivoted inthe slide, the arm H and its hook h, the lever H", operatedsubstantially as'shown, the grip-rod H and the feed-plate G, as setforth.

8. The combination, with the pitman, of the slide and the pincher-shearsoperated in connection therewith, substantially as shown, to grip thetwine during the left throw of said slide, to tighten the knotand tosever the twine just after the right throw begins, as set forth.
